Ball detector module.
Can be used to count or detect the number of balls. Works with a hall chip built into the module. A small Neodym magnet is built into a rotating anchor. In order to measure a series of balls properly, a brake zone is built in. Without this braking zone the anchor will otherwise not have time to move back. The anchor has 2 extra holes of 4 mm. They can be used to place small steel axles as extra counterweight. However, I have tested it even without these extra weights and it works perfectly. The first hole of 4mm also serves to pull out the small magnet if you have the wrong polarity. I made a reference setup so that I have the correct polarity before pressing the magnet.
In the module extra height has been kept free to use Fischertechnik blocks. These are indicated on the drawing. Original Fischertechnik parts are always easier to connect with other parts. These extra parts are also shown in the drawing. The output of the module can be made via a straight connection or a 180 degree connection. All necessary blocks are also shown in the drawing.
For the hall connection I use a 3 pin female connetor. The wires of the hall can be easily connected without additional PCB. I swapped the 2 power pins of the hall output to the connector so the connector would have a standard connection: Output, +VCC, GND. This wiring then corresponds to that of a servo connection. The hall has an open collector output so it can easily be used on any kind of interface. Its power supply itself can be between 4V and 24V. The most commonly used voltage is 5V.
A drawing is also included with the timing results for a burst of 5 balls. You have to take into account that sometimes the speed can be quite high (pulses about 25 msec). You may need to sharpen the brake zone ( adjusts the input so that the ball can just pass) if your controller cannot handle this speed. This is the case for the TXT Controller Fischertechnik. I use my FPGA controller to read the pulses and it never has speed problems.
All parts are printed with the Flachforge Finder 3D printer. The filament used is PLA 1.7mm, 210 degree, Raft and Brim enabled, Infill 25%.

Got a lie detector kit from madlab. It measures galvanic skin response as a means of detecting if someone starts sweating. That being said, it's not very reliable. However, I think I'm going to use it for what it's intended to sense and not for the purpose of it's design.

Note to self: Quite a deep stack at around 5mm. Lost some image balance on head after stack, Found on window, i just had to have a closer look.

Two hours before the campaign of opposition.
-----------------
June 12 was held in Moscow next protest demonstration of opposition. On the march sounded slogans against the government of Putin and his regime. Marsh took place against the backdrop of interrogations the leaders of the opposition movement and the next day after were a large-scale searches.
An unattended radon detection and data logging instrument I built for work. I know... I accidentally installed an under-board SD card slot on the top, so the cards have to be put in upside down. That's embarrassing...

I built this set several years ago using old parts found at auctions along with new parts. The crystal detector was purchased from a man named Clinton Blais - Clint knew more about radio than anyone I have ever known.

An instrument used to detect ferrous (rusty) metals at Old Fort Niagara, Youngstown, NY, July 20, 2020. The seawall along the north shoreline of Old Fort Niagara is experiencing significant deterioration and erosion. A USACE Buffalo District project in development will protect the historic “French Castle” built in 1726 and the North Redoubt, built in 1771.

Located on the PSAP Bangor Sub, this is the last active Burlington Northern defect detector. There used to be two on the PSAP, but the one in Oakville was recently replaced, making this the last one. I had intended to do a low shutter shot at this location, but unfortunately the train arrived much quicker than expected leaving me with this. Allyn, WA, 8/27/2025

Brookhaven National Lab invited both amateur and professional photographers to a three-hour, behind-the-scenes Photowalk of the laboratory on Saturday, Sept. 22, 2012. Participants were able to visit and photograph five major experimental facilities that are not usually accessible to the public including the Relativistic Heavy Ion Collider (RHIC) Tunnel, RHIC’s STAR Detector, RHIC’s PHENIX Detector, National Synchrotron Light Source, and National Synchrotron Light Source II.
